CPU time: The amount of time a thread spends executing on a logical processor. For multiple threads, the CPU time of the threads is summed. The application CPU time is the sum of the CPU time of all the threads that run the application.
CPU usage: A performance metric when the VTune Amplifier identifies a processor utilization scale, calculates the target CPU usage, and defines default utilization ranges depending on the number of processor cores.
finalization: A process during which the Intel® VTune™ Amplifier converts the collected data to a database, resolves symbol information, and pre-computes data to make further analysis more efficient and responsive.
hotspot: A section of code that took a long time to execute. Some hotspots may indicate bottlenecks and can be removed, while other hotspots inevitably take a long time to execute due to their nature.
thread concurrency: A performance metric that helps identify how an application utilizes the processors in the system by comparing the application concurrency level (the number of active threads) and target concurrency level (by default, equal to the number of physical cores). Thread concurrency may be higher than CPU usage if threads are in the runnable state and not consuming CPU time.
viewpoint: A preset result tab configuration that filters out the data collected during a performance analysis and enables you to focus on specific performance problems. When you select a viewpoint, you select a set of performance metrics the VTune Amplifier shows in the windows/panes of the result tab. To select the required viewpoint, click the button and use the drop-down menu at the top of the result tab.
Wait time: The amount of time that a given thread waited for some event to occur, such as: synchronization waits and I/O waits.
